The Low-Density Supersonic Decelerator project will demonstrate the use of inflatable structures and advanced parachutes that operate at supersonic speeds to more efficiently slow down a spacecraft navigating through planetary atmosphere prior to landing. These new supersonic inflatable and parachute decelerators will increase landed payload masses. They also will allow for higher-altitude landings and access to a larger portion of a planet's surface, and will enable improved targeting of safe landing sites. These new devices will be suitable for infusion into landed Mars missions, greatly extending performance capabilities. Flight testing is planned through 2015. Infusion customers include NASA's Science Mission Directorate and NASA's Human Exploration and Operations Mission Directorate.
